THE RETAINING MEANS PERMITS THE CONTACT ARM ASSEMBLY TO BE REMOVED FROM THE FRAME FOR FULL ACCESS TO AN OPERATING COIL OR COILS WITHOUT THE USE OF A TOOL. PROVISION IS MADE FOR READY INTERCHANGE OF DIFFERENT

CONTACT MAKING AND BREAKING DEVICES AND DIFFERENT OPERATING COILS SO THAT THE RELAY CAN BE USED FOR A WIDE VARIETY OF CIRCUIT CONTROLLING FUNCTIONS.
