GEN3 UMS1-20 20A Single Pole Ultra Mini Isolator Switch 250V IP66

Description

A compact weatherproof isolator for safe circuit disconnection.

The GEN3 UMS1-20 is an ultra mini isolator switch rated 20A, single pole, 250V AC and IP66. An isolator provides a simple, reliable means of manually disconnecting a circuit so it can be worked on safely, for example when servicing an air conditioner, pump or item of equipment. As the ultra mini version it has a particularly compact 85 × 85mm body, making it easy to fit where space is limited, while its IP66 rating suits outdoor and wash-down locations. Top, bottom and side cable entries give flexible wiring.

Safe, Simple Isolation

An isolator switch lets you fully disconnect a circuit for safe servicing or maintenance. The UMS1-20 is a switch-disconnector rather than a circuit breaker, so it provides isolation rather than overload or fault protection, and is commonly used alongside protective devices to give a clear, local point of disconnection for equipment such as air conditioners, pumps and motors.

Ultra Mini and Weatherproof

With its compact 85 × 85mm body, the UMS1-20 fits neatly where larger isolators will not, and its IP66 rating means it is dust-tight and protected against high-pressure water jets for outdoor and wash-down installations. Top, bottom and side cable entries allow the cabling to be run whichever way suits the installation.

Q: What is an isolator switch used for?
A: It provides a manual means to fully disconnect a circuit for safe servicing or maintenance. It isolates the circuit but does not provide overload or short-circuit protection.

Q: What does ultra mini mean on the UMS1-20?
A: It refers to the compact body size, approximately 85 x 85mm, which is smaller than the standard mini isolator, suiting installations where space is limited.
