TECHNICAL DATA SHEET Sentry Switch Disconnectors 1:2 Sentry® Switch Disconnectors Description PRODUCT RANGE Switch disconnector Rating 5500s 100A 5560s 63A The Sentry range offers a choice of switch disconnector rated at either 100A or 63A. The operating dolly is capable of being locked in either the ON or OFF position. When locked in the ON position it will no longer operate as an isolator. Positive indication of the opening of the contacts is only given when the green stripe can be seen on the dolly. The terminals are of a tunnel design and offer a generous cable capacity of 50mm2 for solid stranded conductors and 35mm2 for flexible conductors, on both current ratings. Category of duty The Sentry switch disconnector is capable of switching both resistive and inductive loads and has a category of duty of AC22A. Features ■ Meet BS EN and IEE Wiring Regulation requirements ■ Choice of current ratings ■ Tunnel design terminals for ease of wiring ■ Generous cable capacity ■ Optional terminal shields available ■ Lockable operating dolly ■ Make first, break last on neutral 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 07-01 TECHNICAL DATA SHEET Sentry® Dimensions (mm) Switch Disconnectors 2:2 36 48 16 MAIN SWITCH 72 LN 5500s 100A AC22A 240V 50HZ EN 60947-3 N1 N2 45 L1 L2 ON OFF 44 TECHNICAL SPECIFICATION Electrical Category of duty: AC22A Load type capability: Both resistive and inductive Operating voltage: 240V a.c.
