ER12-16N6SB

Disconnect switch components play an important role in many industrial applications, offering reliable and easy-to-use solutions for safely connecting and disconnecting power. One example of a disconnect switch is the ER12-16N6SB, a dual-pole, single-phase disconnect switch designed for over-voltage and over-current protection.

The ER12-16N6SB is a non-fused type of disconnect switch, meaning it has no internal fuses but relies on external over-current protective devices (OCPDs). It is rated 15 Amps AC for both 120 Volt and 240 Volt applications. It is also UL and CSA certified and certified for use in hazardous locations.

One of the primary applications for the ER12-16N6SB is residential and commercial wiring for lighting and appliance circuits. It is particularly designed for back-fed applications, such as when the switch is used to control the power to a breaker on the load side of the service. The switch can also be used in reverse applications, as an emergency shut-off in the event of an overload or short circuit.

The ER12-16N6SB has two poles. Each of these poles contains a distinctly colored handle, for easier identification and operation. To open the switch, both of these handles can be flipped in the “OFF” position. It is also possible to use the switch as a lighted switch, with an LED indicator light to let you know when the switch is in the “OFF” position.

The ER12-16N6SB utilizes three internal contacts: two prong contacts and a center contact. These are connected to external wiring via 1/4” push-in terminals. A wire-spliced connection using a wirenut is required.

The working principle of the ER12-16N6SB is simple: the contacts between the two prong blades (the “input” contacts) and the contact connected to the internal coil (the “output” contact) are broken when the switch is in the “OFF” position. When the switch is in the “ON” position, the contacts are closed, allowing power to flow between the two poles.

The ER12-16N6SB is an important disconnect switch component used in many residential and commercial applications. It is designed to provide a reliable and easy to use solution for safely connecting and disconnecting power. With its two poles and UL/CSA certification, it is well suited for many applications where over-voltage and over-current protection are crucial.
