New undervoltage trip releases for SM1P type motor protection circuit breakers



Designed for the protection and safety of machines, especially hazardous ones, LOVATO Electric undervoltage trip releases combine innovation with functionality.

Their main task is to open the motor protection circuit breakers when mains voltage fails, and hence prevent the motor from starting unexpectedly when power is restored. They are used primarily in small machines, in which motor control and stopping are handled exclusively by the motor protection circuit breakers.

Carefully designed for continuous service, the new SM1X15...P undervoltage trip release is also ideal for opening SM1P type motor protection circuit breakers when actuated by an emergency stop button or limit switch. The disconnector can be installed inside a wall-mounted or flush-mounted plastic enclosure near the machine.

SM1X15...P undervoltage trip releases have an another advantage over standard products: they have integrated normally-open early make contacts.
This function means that whenever the motor starter is set to OFF, the coil is disconnected, which interrupts the consumption of power and its subsequent thermal dissipation. Another feature of the product is that it can be used to switch off power to other components connected in series to the undervoltage trip release coil (such as emergency stop buttons and limit switches).

4 part codes are available, depending on the coil voltage.

The product is just 18 mm wide, and mounts to the right side of the SM1P motor protection circuit breaker quickly and easily by just snapping it on.

This accessory has an IP20 protection degree and is cULus and EAC approved.
