Under-voltage module UV with delay 24-30V AC/DC (UVTC) HWY030H

Acts as "memory" for air circuit breakers

The UVTC HWY030H module does not operate independently — it is connected to an hw+ air circuit breaker to add an under-voltage delay function. When voltage drops below a threshold value, the module prevents re-energization for a preset time — this is crucial for equipment that should not automatically restart after a brief power interruption. Example: a heat pump or compressor — we do not want them to start immediately when voltage returns after a lightning strike.

Protects against improper power supply

Operates with a control voltage of 24–30 V AC/DC — meaning it works with both alternating and direct current. There is no need to worry about the network type if the system is built on low control voltages. Wires are connected directly to terminals: cross-section from 0.6 to 2.5 mm², suitable for both solid and flexible conductors. This means no additional cable lugs or adapters are required — installation is simple and fast.

No impact on the environment or installation

Protected to IP4X rating — prevents entry of objects larger than 1 mm in diameter. This is sufficient for installations in dry or slightly damp rooms. It is not intended for outdoor or wet locations, but operates safely within a distribution board. Operates in temperatures from -25°C to +70°C — so even in cold storage facilities or under strong heating inside a cabinet, functionality is maintained.

Mounting only to hw+ circuit breakers

This accessory works exclusively with hw+ series air circuit breakers. It cannot be connected to other brands or even to older Hager models. It is a system component — designed to fit perfectly with the terminals and control mechanisms of these specific circuit breakers. If you have hw+, this module is a natural extension of its functionality.
