Shacman X5000 Master Power Switch is an OEM-grade battery isolation system designed for Shacman X5000 heavy trucks. It allows instant disconnection of the entire electrical system, preventing parasitic drain, short circuits, and fire hazards. This comprehensive kit includes every mounting and fastening component required for a professional installation: an installation bracket for power, the master power switch itself, bolts, 2 type all metal hexagonal lock nuts, flat washers, and spring washers. Each part is engineered to withstand vibration and harsh environments.
The installation bracket for power is fabricated from 3mm thick galvanized steel with precision stamped mounting holes. It securely holds the master power switch onto the vehicle chassis or battery tray. The bracket features anti-rotation ribs and rubber edge trim to reduce vibration transfer. Powder-coated in black with 500h salt spray resistance, it ensures long-term reliability even in corrosive environments. Direct fit for Shacman X5000 predefined mounting points.
The master power switch is rated for 300A continuous (1500A peak interrupt) and features silver-plated copper contacts for minimal voltage drop. Its rotary lever action provides tactile feedback and requires deliberate force to operate, preventing accidental disconnection. Sealed to IP67, the switch withstands dust, high-pressure washing, and temporary submersion. The housing is reinforced with glass-filled nylon for impact resistance. Perfect for 12V/24V systems, this master power switch is the core of the safety system.
These bolts (M6x20mm, property class 8.8) are used to attach the installation bracket and switch assembly. Manufactured from medium carbon steel with zinc-plated finish, they provide excellent tensile strength and corrosion protection. The hexagon head allows for easy torquing with standard 10mm sockets. Each bolt features full thread engagement and a chamfered point for hassle-free alignment during assembly.
These all-metal hexagonal lock nuts (M6, type 2) provide prevailing torque locking without any non-metallic insert. The elliptical thread distortion creates constant friction against the bolt, preventing loosening from vibration. Reusable up to 5 times with consistent clamping force. Phosphate coated for corrosion resistance, they operate reliably from -50°C to +150°C. Two locknuts secure the critical connections of the master power switch assembly.
These flat washers (6mm ID / 12mm OD) are made of hardened steel with bright zinc plating. Installed under the bolt head and locknut, they distribute clamping pressure evenly, preventing damage to the bracket’s painted surface. The washers also reduce friction during torquing, ensuring accurate preload. Each flat washer conforms to DIN 125A standards for consistent dimensions.
The spring washer (M6, helical type) provides additional resilience against dynamic loads. When compressed, it exerts a constant axial force that maintains tension even if the bolted joint experiences minor loosening. Ideal for heavy-truck applications where continuous vibration is present. These spring washers are used in conjunction with flat washers to optimize locking performance for the Shacman X5000 master power switch mount.

IP67 (switch), IP54 (bracket)The installation bracket for power is laser-cut and formed to match the Shacman X5000 chassis rail pattern. It features two M6 threaded mounting holes pre-aligned with the master power switch base. Rubber grommets at cable entry points protect the wiring from sharp edges. Bracket thickness: 3.0mm, material: DX51D+Z275 galvanized steel.
Two bolts (Q150B0620) together with two type all metal hexagonal lock nuts (Q33206) provide the primary securing force. Flat washers (Q401B06) protect the bracket surface while spring washers (Q40306) add resilience. Recommended torque: 10-12 Nm. The all-metal locknuts maintain prevailing torque even after repeated thermal cycles.
Step-by-step: 1) Disconnect negative battery terminal. 2) Mount the installation bracket for power using existing chassis holes. 3) Attach master power switch to bracket using bolts, flat washers, spring washers and locknuts. 4) Connect battery positive cable to switch input terminal, and starter/load cable to output terminal. 5) Torque terminal nuts to 20 Nm. 6) Reconnect negative terminal and test switch operation.
Every Shacman X5000 Master Power Switch kit is batch-tested: the master power switch undergoes 10,000 mechanical cycles and 500 electrical cycles at rated current. Bolts and locknuts are verified for tensile strength and torque retention. The installation bracket for power is checked for dimensional accuracy using CMM. All fasteners pass 520h salt spray test (ASTM B117). The complete assembly is vibration tested per ISO 16750-3 (20g, 24 hours).
Reduce battery replacements: Disconnect batteries during long parking periods, eliminate parasitic drain by 100%, extend battery life up to 40%.
Faster maintenance: Quick isolation without removing terminals. Improves workshop safety for electrical repairs, welding, or component replacement.
15-minute installation: All hardware included, no fabrication required. Fits directly on Shacman X5000, X3000, and X6000 series.
Global availability: Stock in regional warehouses, same-day dispatch for urgent fleet orders.
Fleet feedback indicates that the Shacman X5000 Master Power Switch reduces electrical-related roadside breakdowns by 67%. The all-metal locknuts and spring washers maintain clamping force even on gravel roads, while the IP67-rated switch continues to operate after pressure washing.
The master power switch (DZ97189763036) directly replaces original part numbers 81.25470.0042 and 81.25470.0045. The installation bracket for power (DZ97189763032) fits Shacman X5000 years 2018–2026, as well as X3000 and X6000 chassis with rear battery mounting. For retrofit applications, the bracket can be adapted using universal mounting holes.
Does the master power switch handle 24V systems? – Yes, rated for 12V and 24V DC. The silver contacts are designed for 24V arc suppression.
Can I reuse the all-metal locknuts if I disassemble? – Yes, type 2 all metal hexagonal lock nuts can be reused up to 5 times while still meeting prevailing torque specs per IFI-124.
Do I need to replace flat washers and spring washers? – Included in the kit; they are reusable but we recommend new ones for optimal performance. Spring washers maintain shape after several cycles.
Is the installation bracket for power painted or raw? – Powder-coated semi-gloss black, 80µm thickness, edge coverage for corrosion resistance.
What torque for the master power switch terminal studs? – 18–22 Nm for M10 studs. Do not overtighten to avoid damaging the plastic base.
