Hager RCCB Type A 100A 100mA Triple Pole & Neutral CEA684U

Hager CEA684U: 100A 3P+N RCCB (Residual Current Circuit Breaker) with 100mA Type A sensitivity, built for reliable earth fault protection in circuit protection applications.

Safety & Reliability

The CEA684U is a Type A residual current circuit breaker with a rated residual operating current (Idn) of 100mA, giving dependable protection against earth leakage faults. It carries a rated conditional short-circuit current (Inc) of 10kA to EN61008-1 and a breaking and opening capacity (Idm) of 1.25kA, so it's built to withstand fault conditions without compromising the circuit. Rated insulation voltage is 500V, with a dielectric strength of 2kV and rated impulse withstand voltage of 4000V (6000V to IEC 60947-3), confirming its ability to handle voltage surges. The enclosure carries an IP20 ingress protection rating.

Installation & Compliance

Designed for standard DIN rail mounting across 4 modules, the CEA684U uses screw terminals at the top (biconnect at the bottom) with aligned terminal connections at both ends, simplifying installation in distribution boards. Terminal tightening torque is 3.60Nm at both top and bottom connections. Conductor cross-sections accepted range from 1 to 50mm² for solid (massive) conductors and 1 to 35mm² for flexible conductors, at both input and output. The unit is RoHS conform.

Performance & Endurance

Rated at 100A with an operational voltage (Ue) range of 230 to 400V AC and a frequency range of 50 to 60Hz (max. operating voltage 440V), the CEA684U suits 3-phase and phase-plus-neutral installations. It's rated for electrical endurance of 10,000 cycles and 20,000 mechanical operations, giving a long service life under repeated switching. Power dissipation at rated current is 21.48W. The device operates reliably across a temperature range of -25°C to 60°C and at altitudes up to 2000m.

Test & Indication

A built-in test button lets installers and maintenance teams verify trip function directly on site, supporting regular periodic testing. A position contact indicator shows the current switch state, making status checks quick and straightforward during inspection or fault-finding.
