Overvoltage trigger Z-ASA/230 248287

Overcurrent trip device – reliable protection and signaling

The overcurrent trip device Z-ASA/230 is an element used to monitor and signal current increase in a circuit. Its task is to react quickly to irregularities, which translates to increased safety of the electrical installation and connected devices. It is mounted on a TH35 rail, which facilitates its integration with existing systems.

Functionality and application

The device is designed to work with overcurrent circuit breakers, acting as an additional protection against the effects of overloads and short circuits. The overcurrent trip device finds application in electrical installations in residential, commercial and industrial buildings. Thanks to its design and parameters, it is particularly useful where high reliability and a quick response to load changes are required.

• Current monitoring: Continuous control of the current value in the circuit.
• Signaling: If the set threshold is exceeded, the trip device activates an auxiliary contact, allowing connection of optical or acoustic signaling.
• Protection: Supports protection against the effects of overloads and short circuits, increasing installation safety.
• Mounting: Easy mounting on a TH35 rail using a snap-in mechanism – speed and convenience of installation are a key advantage.

Technical characteristics and construction

The Z-ASA/230 trip device is characterized by a compact design with a width of 1 module, which allows saving space in the switchgear cabinet. It has one normally open contact (1NO) and one normally closed contact (1NC), which provides flexibility in configuring control and signaling circuits. The device operates at a rated voltage of 415 V AC and is adapted to cooperate with circuits with a maximum current of 15 A. The construction based on proven EATON technology ensures long-lasting and trouble-free operation of the device. The lack of a residual current device self-test function means focusing on the basic function – monitoring current increase.
