Fuse block with door sensing rotary disconnect
First Claim
1. An disconnect mechanism for a fuse block receiving power connections and of a type having a support face for mounting on a panel with one or more fuse sockets accessible on a front face of the fuse block opposite the support face and with a rotary operator extending outward along a side face of the fuse block to be substantially perpendicular to a panel on which the fuse block is mounted, an outer end of the rotary operator adapted to receive a portion of a door mounted handle and rotating to disconnect the fuses from the power connections, the improvement comprising:
- a side mounted lock out positioned proximate the side face and including;
(a) a sensing arm having a first end positioned near an outer end of the rotary operator to be depressed inward with engagement of the outer end of the rotary operator and the door mounted handle; and
(b) an operator lock communicating with the sensing arm and engage the rotary operator to allow rotation of the rotary operator only when the sensing arm is depressed.

Abstract
A fuse block having a rotary operator communicating with a door-mounted knob provides a sensor arm on the rotary operator for engaging the door handle to detect closure of the door. A slider may actuate a set of plates capturing a swing arm attached to the rotary operator preventing inadvertent movement of the rotary operator when the door is open.
