An undervoltage release automatically trips a circuit breaker when the supply voltage drops below a safe operating level, protecting connected equipment from damage.
The A9N26960 requires a control voltage of 220-240V AC at either 50Hz or 60Hz.
It is compatible with Schneider Electric Acti 9 series circuit breakers including C40, C60, DT40, IDPN, DT60, C120, DPN Vigi, ITG40, IDc, and ID C40.
The device has a width of 18 mm, a height of 73.5 mm, and a depth of 82.5 mm.
No, this undervoltage release is designed specifically for AC control voltages (220-240V AC) and is not suitable for DC systems.
It features screw terminals for electrical connection.
The operating temperature range is from -25 °C to 50 °C.
Verify the control voltage is within the 220-240V AC range. Ensure the coil is correctly wired and securely connected to the circuit breaker. Check that the circuit breaker itself is functioning correctly.
Inspect wiring for loose connections or damaged insulation. Check for sources of electrical noise or interference that might be affecting the coil's operation. Ensure the ambient temperature is within the operating range.
Confirm that the circuit breaker is from a compatible Acti 9 series. Ensure no obstructions are present on the mounting interface of both the breaker and the coil. Refer to the specific mounting instructions for the connected circuit breaker.
Setup: The A9N26960 undervoltage release is designed to be mounted on the side of compatible Schneider Electric Acti 9 circuit breakers. Ensure the main power is completely disconnected before installation. Connect the control wires to the screw terminals according to the wiring diagram provided with the circuit breaker or the undervoltage release. Mount the unit securely to the breaker.
Compatibility: This undervoltage release is specifically designed for use with the following Schneider Electric Acti 9 series circuit breakers: C40, C60, DT40, IDPN, DT60, C120, DPN Vigi, ITG40, IDc, and ID C40. It requires a control voltage of 220-240V AC at 50Hz or 60Hz.
Care: Minimal care is required. Periodically inspect the connections to ensure they remain tight. Keep the area around the device clean and free from dust and debris. Avoid exposure to excessive moisture or extreme temperatures outside the specified operating range (-25 to 50 °C).
