HO232-60/HO234-40 Residual Current Circuit Breaker With Over-Current Protection (RCBO)
It is electro-mechanical in nature. The highlight here is that:
Specification
By combination with miniature circuit breaker => RCBO-Unit (MCCB) Add-on residual current unit (screw connection) for 80 or 125 A (2-pole and 4-pole)
• High flfl exibility and ease of installation thanks to variable wiring (400 mm flfl exible connection wires 2p = 2 units, 4p = 4 units included in the set)
• Free selection of main power supply
• Auxiliary switch 1 NO included as standard in all FBHmV versions
• Permits combinations with a variety of characteristics thanks to the different rated currents and characteristics of the miniature circuit breakers AZ which can be connected
• For trade and industry applications
• For subsequent mounting onto 2, 3, 3+N and 4-pole-miniature circuit breakers
• Toggle (serves as switch position- and tripping indicator)
• The screw connection to the device can be unscrewed at any time. Consequently, in case of modififi cations of the systems to be protected, the installation can be adapted to new requirements at any time.
• The test key “T” must be pressed every 6 months. The system operator must be informed of this obligation and his responsibility in a way that can beproven. Under special conditions (e.g. damp ly and/or dusty environments,environments with polluting and/or corroding conditions, environments with large temperature flfl uctuations, installations with a risk of overvoltages due to switching of equipment and/or atmospheric discharges, portable equipment...), it’s recommended to test in monthly intervals.
• Pressing the test key “T” serves the only purpose of function testing the residual current device (RCD). This test does not make earthing resistance measurement (RE), or proper checking of the earth conductor condition redun dant, which must be performed separately
