Safety Switches

ABB Spec-Setter Safety Switches provide rugged, reliable power switching for residential, commercial, industrial, and utility service entrance applications. Easy-to-install and easy-to-use, our cUL and CSA-certified safety switches are built to last. When it comes to safety, we know: The safer, the better. 

 

Electrical Safety Switches for Reliable Power Control

An electrical safety switch, also known as a safety disconnect switch, protects against electric shock by providing a manual circuit disconnection point. Vital for maintenance and emergency shutoff, they isolate circuits with a clear, lockable lever or switch, ensuring a safe operating environment. 

The ABB Spec-Setter safety switch series is suitable for installations across commercial and residential buildings, manufacturing and industrial sites, utilities service entrance, HVAC systems, and more.  Built with durability and ease of installation in mind, each Spec-Setter model is both cUL and CSA certified.

Our portfolio of General Duty, Heavy Duty, Double Throw, and Emergency Power Transfer safety switches ensures that no matter the application, we’ve got you covered.

Double Throw

Both Type TC and TDT double-throw safety switches are designed for applications with two sources of power. Their “stacked” fusible design saves money and simplifies handling by using one common set of fuses for either source of incoming power.

Frequently Asked Questions


What type of safety switch do I need?

Choosing the right safety switch depends on your environment, electrical load, and use case. For residential and light commercial applications, use general duty safety switches. Heavy duty switches are designed to withstand industrial, commercial, and utility service entrance environments and applications. Use double-throw switches when your facility has two power sources to manage, or emergency power transfer switches for back-up power systems.

Other considerations include: Fusible vs. non-fusible, fuse type compatibility, enclosure requirements, and certification rating. 

When do I need a fusible or non-fusible safety switch?

Use fusible switches when you need overcurrent protection in addition to circuit disconnection controls. Non-fusible safety switches only provide circuit disconnection. They are for when overcurrent protection is already provided by an upstream circuit breaker. ABB provides both fusible and non-fusible options across its general duty, heavy duty, and double throw safety switches. ABB emergency power transfer switches are only available as non-fusible.

What is the difference between a fusible safety switch and a circuit breaker?

A fusible safety switch provides a visible disconnection point that isolates an electrical circuit and provides some overcurrent protection. This enables safe service and maintenance as well as emergency shutoff. A circuit breaker, by contrast, is designed to automatically protect against overloads or short circuits, but does not provide a visible disconnection point.
