TECHNICAL DATA SHEET Sentry Switch Disconnectors 1:2 Sentry Switch Disconnectors Description PRODUCT RANGE Switch disconnector Rating The Sentry range offers a choice of switch The terminals are of a tunnel design and offer 2 disconnector rated at either 100A or 63A. a generous cable capacity of 50mm for solid 5500s 100A 2 stranded conductors and 35mm for flexible The operating dolly is capable of being locked 5560s 63A conductors, on both current ratings. in either the ON or OFF position. When locked in the ON position it will no longer operate as Category of duty an isolator. Positive indication of the opening The Sentry switch disconnector is capable of of the contacts is only given when the green switching both resistive and inductive loads stripe can be seen on the dolly. and has a category of duty of AC22A. Features Meet BS EN and IEE Wiring Regulation Generous cable capacity requirements Optional terminal shields available Choice of current ratings Lockable operating dolly Tunnel design terminals for ease of Make first, break last on neutral wiring Standards and approvals Sentry switch disconnectors are designed to fully comply with the requirements of BS EN 60947-3. They feature positive contact status indication in accordance with the 16th edition IEE Wiring Regulations 537-02-03 and 537-03-02. The Sentry switch disconnector may therefore be used as an isolating switch. 2001 MK Electric Limited The Arnold Centre, Paycocke Road, Basildon, Essex SS14 3EA, United Kingdom Tel: +44 (0)1268 563720 Fax: +44 (0)1268 563064 email: more mkelectric.co.uk www.mkelectric.co.uk Edition 07-01TECHNICAL DATA SHEET Sentry Dimensions (mm) Switch Disconnectors 2:2 36 48 16 MAIN SWITCH N1 L1 LN 5500s N2 L2 100A AC22A 240V 50HZ ON 45 72 OFF EN 60947-3 44 TECHNICAL SPECIFICATION Electrical Category of duty: AC22A Load type capability: Both resistive and inductive Operating voltage: 240V a.c.
