Description
The WB1LE-125H is a high-breaking-capacity miniature residual current circuit breaker for AC 50/60 Hz circuits rated 230 V (1P+N, 2P) or 400 V (3P+N, 4P) and up to 125 A. When electric shock or leakage current exceeds the set value it cuts off the faulty supply quickly, and it also protects circuits and motors against overload and short circuit.
Protection
- Fast cut-off when shock or leakage current exceeds the set value.
- Overload and short-circuit protection for circuits and motors.
- Rated current up to 125 A at AC 50/60 Hz.
Where it fits
- Industrial and commercial distribution boards.
- Circuits and motors needing shock and leakage protection.
- Projects needing a high-rated RCBO in a compact device.
Selection and ordering
Confirm the rated voltage and pole configuration, the load current, the residual current sensitivity and whether infrequent motor starting must be supported. We will confirm the correct model and provide a quotation.
FAQ
How is the WB1LE-125H different from the WB1LE-63?
The WB1LE-125H extends the rated current up to 125 A, making it suitable for larger circuits and motors that need combined residual current and overcurrent protection.
How quickly does it respond to leakage?
When electric shock or leakage current exceeds the set value, the device cuts off the faulty supply in a very short time to protect people and equipment.
Can it protect motors?
Yes. It protects motors against overload and short circuit and can be used for infrequent motor starting.
