Residual Current Circuit Breaker 2P 40A 30mA Type A 6kA EFI6-P2 by Eti-Polam

Eti-Polam EFI6-P2 is a 2-pole residual current circuit breaker rated for 40 A with 30 mA sensitivity and Type A detection. Designed for protection against earth leakage and both AC and pulsating DC fault currents, this device combines residual current detection with overcurrent interruption capability up to a short‑circuit capacity of 6 kA. The compact, two‑pole format makes it suitable for single‑phase distribution boards in residential and light commercial environments where personnel and fire safety are required.

Advantages

The EFI6-P2 offers reliable residual current detection with 30 mA sensitivity to reduce the risk of electric shock and to help prevent fire caused by earth faults. Type A detection extends protection to pulsating DC fault currents in addition to standard AC leakage, broadening applicability for modern loads. With a 6 kA breaking capacity and 40 A rated current, the device provides coordinated protection for typical branch circuits while fitting standard DIN-rail distribution assemblies.

Suitable for

• Residential single‑phase circuits (lighting, sockets, small appliances)
• Light commercial installations (offices, retail outlets)
• Circuits with electronic loads that may generate pulsating DC leakage
• Replacement or upgrade of existing two‑pole RCDs in consumer units

When it may not be suitable

This residual current circuit breaker is not intended for three‑phase installations or for circuits requiring protection above 40 A. It does not provide selective coordination for complex distribution systems where time‑delayed or type B/GF‑sensitive devices are required. For installations with pure DC fault risks or industrial equipment generating high-frequency leakage, a different RCD type or additional protective measures may be needed.

Key specifications

• Poles: 2‑pole (single‑phase)
• Rated current: 40 A
• Residual operating current: 30 mA (0.03 A)
• Sensitivity type: Type A (AC and pulsating DC detection)
• Breaking/short‑circuit capacity: 6 kA
• Mounting: DIN‑rail compatible, compact two‑module width

How to use

Install the EFI6‑P2 in the consumer unit on a standard DIN rail and connect the line and neutral conductors to the marked terminals following local wiring regulations. Ensure the device is placed upstream of the circuits it protects and that downstream overcurrent protection is coordinated. After wiring, test the RCD operation using the built‑in test button to confirm tripping at regular intervals and after installation. Observe all safety procedures and, where required by regulations, have the installation verified by a qualified electrician.

What to consider before purchase

• Verify the installation is single‑phase and requires a 40 A rated device.
• Check that Type A sensitivity is appropriate for connected electronic equipment.
• Confirm available panel space and DIN‑rail mounting compatibility.
• Ensure downstream circuit breakers are compatible with a 6 kA breaking capacity.

Usage recommendations

Test the residual current circuit breaker monthly using the test button and after any maintenance or changes to the circuit. Use this device as part of a coordinated protection scheme together with appropriate overcurrent protection and earthing arrangements to maintain safety and compliance with local electrical codes.
