Datasheet

Hylec-APL has announced new model in its range of ISOLATOR switches, which provide fast electrical isolation for multiple applications, including industrial machinery, commercial buildings, power supplies, security equipment and HVAC. ISOLATOR control switches are IP67 rated and withstand water up to a depth of one metre, as well as completely preventing the ingress of dust and dirt, vital in many factory and commercial applications.

Safety is of paramount importance in such environments, and ISOLATOR control switches ensure an electrical circuit is completely de-energised for routine service and maintenance and can be shut down quickly in the unlikely event of an emergency.

The ISOLATOR switch separates the circuit from the main power source and discharges any current trapped in the circuit, rendering it safe to work on and of course ensuring fast shut down and the absence of any electrical current when an emergency stop is required.

When used as an emergency stop, it can be locked in the off position using a padlock (not supplied). For safety, the switch is interlocked with the lid to prevent opening while in the “on” position. The interior mechanism is a 4-pole rotary isolator switch disconnector used to switch power to commercial or light industrial applications.

ISOLATOR control switches are manufactured from completely flame retardant polycarbonate, rated to UL94V-0, providing an additional margin of safety over competitive products with a lower flame-resistance rating. As well as being flame retardant, housings are robust and highly visible, with yellow covers and red control switches.

The new 80A AC ISOLATOR model features silver-plated alloy contacts for high reliability. Earth terminals are included, as well as captive retained cover screws. The 80A AC ISOLATOR has a compact footprint, but its internal dimensions are a generous size, measuring 9cm wide by 17.3cm long, so there is space to manipulate cables easily during installation.
