Description

The WB1LE-63 is a residual current circuit breaker (RCBO) for AC 50 Hz circuits rated 230 V (1P+N, 2P) or 400 V (3P, 3P+N, 4P) and up to 50 A. It provides indirect-contact protection for people and overcurrent protection for building installations, and helps protect against fire caused by persistent earth faults that overcurrent devices do not clear.

Protection

  • Residual current (earth-leakage) protection against electric shock.
  • Overload and short-circuit protection.
  • Protection against fire caused by persistent earth faults.
  • Over-voltage protection version available.

Where it fits

  • Residential and commercial distribution boards.
  • Circuits requiring protection of people against indirect contact.
  • Installations needing combined leakage and overcurrent protection.

Selection and ordering

Confirm the rated voltage and pole configuration, the load current and the residual current sensitivity required, and state whether over-voltage protection is needed. We will confirm the correct model and provide a quotation.

FAQ

What is an RCBO used for?

An RCBO such as the WB1LE-63 combines residual current (earth-leakage) protection with overcurrent protection, protecting people against indirect contact and protecting circuits against overload and short circuit.

Where should residual current protection be installed?

Commonly on circuits feeding socket outlets and equipment, where it also helps prevent fire caused by persistent earth faults.

Is an over-voltage version available?

Yes. An over-voltage protection version is available for circuits at risk from excessive grid voltage.
