Description

The BG CUR4030A-02 bidirectional Type A RCD provides dependable 30mA earth-leakage protection for modern domestic and commercial electrical installations. Rated at 40A, it monitors current flow and rapidly disconnects the supply when a potentially dangerous residual-current imbalance is detected, helping protect people against electric shock.

The BG 40A bidirectional RCD is ideal for electricians and renewable-energy installers searching for a 40A 30mA RCD, Type A double-pole RCD, solar PV bidirectional RCD, EV charger residual-current device, two-module DIN-rail RCD or BG consumer-unit RCD. BG’s circuit-protection range is backed by a ten-year warranty.

Specification

The BG CUR4030A-02 is a 40A, 30mA Type A bidirectional residual-current device. It provides earth-leakage protection in compatible domestic, commercial, solar PV and EV charging installations where current may flow in either direction.

Its double-pole design disconnects both live and neutral conductors. The device occupies two DIN-rail modules, operates at 230V, accepts cable sizes up to 35mm² and has an operating temperature range of -25°C to +40°C.

FAQ's

What does the BG CUR4030A-02 do?

It monitors the electrical current flowing through a circuit and disconnects the supply if it detects a residual-current imbalance or earth-leakage fault above its operating threshold.

What is the current rating?

The CUR4030A-02 has a 40A rated current and a 30mA residual-current sensitivity.

Is this RCD bidirectional?

Yes. It is designed to operate in installations where electrical current can flow in either direction, including suitable solar PV and EV charging applications.

Is it a double-pole RCD?

Yes. The double-pole mechanism disconnects both the live and neutral conductors when the device trips.

Does it protect against overloads?

No. An RCD provides earth-leakage protection. It must be used with correctly selected overcurrent protection because it does not provide the combined overload and short-circuit protection of an RCBO.

How much consumer-unit space does it require?

The RCD occupies two DIN-rail modules and is approximately 36mm wide.

What is the maximum terminal capacity?

BG lists a maximum terminal capacity of one 35mm² conductor.

How quickly does it trip?

The official product data lists a trip speed of less than 0.1 seconds.

What operating temperature does it support?

It is designed to operate in ambient temperatures from -25°C to +40°C.

What warranty is included?

BG’s circuit-protection range is supported by a ten-year warranty, subject to the manufacturer’s terms and conditions.
