| Attribute | Description |
|---|---|
| Part Number | WB372200960 |
| Alternative OEM Number | 3722 Series (Yutong Internal Code) |
| Product Name | Mini Blade Auto-Reset Circuit Breaker |
| Function | Overcurrent protection with automatic reset |
| Application Vehicle Type | Large Passenger Buses, Coaches, Electric Buses |
| Electrical System | 24V DC (Standard Commercial Bus Voltage) |
| Mounting Style | Plug-in (Blade Terminal – Compatible with Standard Fuse Box Slots) |
| Housing Material | Flame-Retardant ABS Plastic (Yellow or Natural Color) |
| Dimensions (L × W × H) | Approx. 50mm × 50mm × 10mm (1.97" × 1.97" × 0.39") |
| Weight | ~0.5 kg (1.1 lbs) |
| Reset Type | Automatic (Type I or Type II thermal reset mechanism) |
| Operating Principle | Bimetallic strip heats and bends under overcurrent → opens circuit → cools → resets |
