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, and the handle is padlockable for secure isolation during maintenance.

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.

Padlockable for Lockout

The handle can be padlocked in the off position, providing secure isolation during maintenance and supporting safe lockout procedures. Moulded from PCA18 virgin-grade plastic with 316 stainless steel springs and screws, the UMS1-20 is built for durability and is covered by Australian/NZ approval or compliance certificates.

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.

Q: Can the UMS1-20 be locked off?
A: Yes. The handle is padlockable in the off position for secure isolation and lockout during maintenance.
