Bill Halyester Local Isolators
3 or 4 Pole, 20A to 1000A, IP65

A new range of heavy duty local isolators within robust IP65 moulded enclosures encompassing a choice of 3 or 4 pole switch units from 20A to 1000A.

Switches are suitable for on load switching of general distribution A.C. power circuits and infrequent duty motor isolation providing excellent AC22A and AC23A ratings.

Compact, high IP rated enclosures make Bill Halyester suitable for most indoor and outdoor environmental conditions. External, adjustable fixing feet are included which do not encroach on the integrity of the enclosure. Enclosures are fitted with suitable gland plates.

Device handles are padlockable in the 'OFF' position with up to 3 padlocks.

For normal ratings up to 63A cable connection is provided for; ratings between 125A and 630A accept both cable and copper connections. The enclosure design allows easy access for cabling and includes earth termination points as standard.

Switch units comply with BS EN 60947. Positive contact indication is provided.
