BG CUR10030BHP 100A Double Pole 2 Module 30mA Bi-Directional Type B RCD – Heat Pump Specification

The BG CUR10030BHP is a 100A double pole Type B RCD designed to meet the demanding requirements of modern heat pump installations and advanced electrical systems. Offering 30mA residual current protection and bi-directional functionality, this 2-module device provides reliable protection against AC, pulsating DC and smooth DC earth fault currents.

Engineered for applications where standard Type A RCDs are not suitable, the CUR10030BHP is ideal for renewable energy systems, EV-related circuits and heat pump installations that may generate DC residual currents.

Key Features

• Rated current: 100A
• Residual operating current: 30mA
• Type B RCD – detects AC, pulsating DC and smooth DC fault currents
• Double pole switching
• Bi-directional – suitable for installations with power flow in either direction
• 2 module width
• Designed to meet heat pump specification requirements

Designed for Heat Pump & Renewable Applications

Heat pumps and other inverter-driven equipment can generate smooth DC residual currents that standard RCDs may not detect. The Type B configuration ensures full protection in these applications, supporting compliance with current wiring regulations and manufacturer requirements.

The bi-directional capability makes this device suitable for systems where energy flow may reverse, such as renewable or grid-connected installations.
