Actuators and mounting accessories PBXR 8325 with referenced accessories Roller lever Mounting plates Accessory kit 83250 Installation recommendations See “Basic technical concepts”. To observe the required clearances and creepage distances in the connection area : - above 125 V: an insulating plate is needed when the switch is mounted on an uninsulated surface. - above 250 V: insulating plates are needed between switches when ganging. How to order Use the 8 digit part numbers when they are defined Other cases, precise: Type of microswitch - Degree of protection - Connection - Actuator* - Mounting...
