HAGER CDF540D interruptor diferencial 2P 40A 30mA tipo F 10kA

Electrical installations with modern loads such as frequency converters or single-phase PV inverters can cause unwanted tripping of standard residual current devices. The HAGER CDF540D residual current circuit breaker (RCCB) is designed to detect residual currents reliably while remaining immune to smooth DC residual currents up to 10 mA, preventing nuisance tripping and ensuring continuous protection.

Who is it for

Electricians and panel builders who need a dependable residual current protection device for circuits with electronic loads, including those with a mix of frequencies or DC components. Suitable for residential, commercial, and light industrial distribution boards.

Main features

• Type F residual current protection: detects AC and pulsating DC residual currents, and is immune to smooth DC residual currents up to 10 mA.
• 2-pole (2P) design for single-phase 230 V AC circuits.
• Rated current 40 A, rated residual operating current 30 mA for personal and fire protection.
• Short-circuit breaking capacity 10 kA according to EN 61008.
• Compact 2-module width for DIN rail mounting.
