Liquid Drainage Eaton’s Cutler-Hammer pushbutton operators offer front of panel drainage via holes in the operator bushing. Hidden from view by the mounting nut, these holes prevent buildup of liquid inside the operator, which can prevent operation in freezing environments. The holes also provide a route for escaping liquid in high pressure washdowns, effectively relieving pressure from the internal diaphragm seal, ensuring reliable sealing in applications even beyond NEMA 4.10250T line operators have “grounding nibs” — four metal points on the operator casting designed to bite through most paints and other coatings on metal panels to enhance the ground connection when the operator is securely tightened.

Benefits 

■ Reliability nibs improve contact reliability even under dry circuit and fine dust conditions 

■ Drainage holes prevent buildup of liquid inside the operator which can prevent operation in freezing environments 

■ Grounding nibs bit through paint and other coatings to provide secure ground Contact Operation Slow make and break. All normally closed contacts have positive opening operation, i.e., normally closed contacts are forced open in the event of contact weld or spring breakage.

Terminals 

■ Marking 

❑ NC-NO on the contact block to meet the NEMA requirements. Dual marking system 1 – 2 for normally closed, 3 – 4 for normally open to meet BS5472 (Cenelec EN50 005) 

■ Clamps 

❑ Terminals are saddle clamp type for 1 x 22 AWG (0.34 mm2) to 2 x 14 AWG (2.5 mm2) conductors 

■ Torque = 7 lb-in (0.8 Nm) 

■ Degree of protection against direct electrical contact: IP2X with fingerproof shroud
