GHG 26 / EXKO 2.. Ex-Safety Switches

Rated current from 10 A – 630 A

CEAG safety switches can be protected against inadvertent switching on by our integrated locking facility for up to three padlocks in the OFF position. To prevent manipulations, the enclosure covers cannot be opened in the locked position without destroying the enclosure itself.

Description

Full AC-3 switching capacity

All CEAG safety switches feature full AC-3 motor switching capacities and isolating properties according to EN 60947-4-1 with compulsory opening of the main current contacts; optional EMERGENCY STOP versions according to EN 60204-1 are also available. An additional lagging/leading auxiliary contacts (option) guarantee double safety for extreme switching conditions.

Installation-friendly design

The safety switches feature an installation-friendly design and easily accessible connection terminals.

Versions in impact-resistant polyamide or glass-fibre-reinforced polyester enclosures provide the high degree of protection IP66 for safety switches up 180 A. These can be optionally supplied with snap-on moulded plastic or brass flanges. Safety switches for amperages up to 630 A are supplied in metal enclosures. These can be equipped with screw-on flanges.

Explosion Group IIB

The described safety switches at the sizes 210 – 630 A are also available for Explosion Group IIB, which is sufficient for many of the applications.Enclosed Switch-Disconnectors to provide isolation during repair and maintenance.

GHG 26 switches (10-160 A) and GHG 981 switches (25 – 80 A) are now confirmed to comply with the new standard IEC 62626-1, requirements Class 1. The new standard IEC 62626-1 defines the requirements for safety switches (switch-disconnectors) that are used to provide isolation of equipment during repair and maintenance. These requirements go above and beyond those of IEC 60947-3, where no standard previously existed.

The standard divides products into two classifications:

Class 0 for general use and
Class 1 for harsh and rough/heavy duty conditions.

All products installed in ATEX/IECEx hazardous areas should be rated for Class 1. Class 1 requirements include minimum ratings for mechanical strength, IP protection, tamper resistance, heat/vibration/corrosion resistance, switching capacity, and locking capability.
