BG CUR6330BHP 63A Double Pole 2 Module 30mA Bi-Directional Type B RCD – Heat Pump Specification

The BG CUR6330BHP is a 63A double pole Type B RCD specifically designed for modern heat pump installations and applications where enhanced residual current protection is required. With a 30mA trip sensitivity and bi-directional operation, this 2-module device provides dependable protection against a full range of fault currents, including AC and smooth DC components.

Type B RCDs are essential where inverter-driven equipment may generate DC residual currents that conventional Type A devices cannot reliably detect. This makes the CUR6330BHP ideal for renewable energy systems and heat pump circuits requiring advanced protection.

Key Features

• Rated current: 63A
• Residual operating current: 30mA
• Type B RCD – detects AC, pulsating DC and smooth DC residual 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

Suitable for Heat Pumps & Advanced Electrical Systems

Heat pumps and other inverter-based systems can produce smooth DC leakage currents. The Type B configuration ensures full detection capability, supporting compliance with current wiring regulations and manufacturer recommendations.

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