Commercial WSB1LE-80 3P+N RCBO
Protect three-phase equipment with WSB1LE-80 3P RCBO. 10-63A, 6kA, 30mA AC type earth leakage protection. Ideal for motors & industrial machinery.
The WSB1LE-80 3P RCBO is a high-performance residual current breaker designed for three-phase, three-wire systems (without neutral). It provides comprehensive protection for industrial machinery and commercial equipment by combining overload, short-circuit, and earth leakage detection in a single, compact unit.
Key Features：
Dedicated 3-Pole Design: Specifically designed for three-phase loads where a neutral conductor is not required, such as motors and pumps.
Triple Protection Function: Combines thermal (overload), magnetic (short-circuit), and residual current (earth leakage) protection in one device.
Wide Industrial Current Range: Available in 10A, 25A, 32A, 50A, and 63A ratings to accommodate various industrial equipment sizes.
30mA Leakage Sensitivity: Provides personnel protection in industrial environments where direct contact with live parts is possible.
Applications:
Industrial Motor Protection
HVAC Systems
Manufacturing Machinery
Agricultural Equipment
