Switch disconnectors can be operated from the outside over door-coupling rotary operating mechanisms even when the control cabinet door is closed.

Rotary operating mechanisms are available in "STANDARD" and "EMERGENCY-STOP" versions and have the following differences:

STANDARD version: masking plate in light gray with black inscription, handle in ti-grey
EMERGENCY-STOP version: masking plate in yellow with black inscription, handle in red

Sizes available

Rotary operating mechanisms	Size	Rated torque¹⁾ Nm	Shaft profile mm x mm	Masking plate mm x mm
8UC71	1	4	6 x 6	75 x 75
8UC72	2	9	8 x 8	75 x 75
8UC73	3	25	10 x 10 or 12 x 12	100 x 100
8UC74	4	40/55²⁾	12 x 12	100 x 100

1) Operating mechanisms tested with triple torque (acc. to EN 60947-3). This also makes them suitable for switch disconnectors.

2) Operation with two hands.

Degree of protection

Degree of protection when installed is IP65.
