  • Configuration: 4-pole (3 phases + neutral)
  • Installation: Quick mounting on DIN rail

Essential robust protection for your high-capacity switchboards.

Hager RCD - 3P+N | 100A | 300mA


Optimise the safety of your industrial or commercial electrical installations with this surface-mounted residual current circuit breaker. Designed by Hager, the industry standard for professionals, this device provides robust protection against earth leakage currents, thereby preventing fire risks and ensuring the safety of equipment.





Key features

  • Configuration: Three-phase + Neutral (4-pole).
  • Rated current: 100A – Ideal for high-power installations or at the top of the distribution board.
  • Sensitivity: 300mA (AC or HI type depending on specific model) – Protection against insulation faults (fire).
  • Connection type: Screw terminals for a secure and durable connection.
  • Format: DIN rail mounting (standard).





Why choose this product?

FAQ - Hager 100A / 300mA RCD

1. Why use a sensitivity of 300mA rather than 30mA? +
The 300mA sensitivity is primarily intended for fire protection and protection against general insulation faults. It is ideal at the head of an installation or for industrial circuits. Conversely, the 30mA is a mandatory high-sensitivity protection for the direct protection of people against electric shocks on terminal circuits (sockets, lighting).
2. Does this device protect against electrical overloads? +
No. A residual current device (RCD ) only detects earth leakage currents. To protect your installation against overloads or short circuits, it must be combined with downstream branch circuit breakers. Its 100A rating indicates the maximum current it can withstand without being damaged.
3. What is the purpose of the 3P+N (4-pole) configuration? +
This configuration is designed for three-phase installations. It allows all three phases and the neutral to be monitored and switched off simultaneously. It is the standard for high-power distribution boards, commercial buildings or industrial workshops.
4. How do you test that the device is working properly? +
Hager has included a test button (‘T’) on the front panel. It is strongly recommended that you press this periodically (approximately once a month) to simulate a fault and check that the tripping mechanism is still working perfectly.
