- Toolless contactor disassembly (sizes 00 to 4) - allows quick access for inspection and maintenance
- Just release 2 retainers and pull a clip to get at magnet, coil and contacts
- Current carrying components - contact tips are weld resistant silver cadmium oxide (fine silver on sizes 00 and 0 only)
- Contacts are installed in a wedge configuration for positive make with minimum bounce
- Class 20 overload protection
- Visual trip indicator with manual reset - to avoid surprise restarts
- Reset occurs on arm upstroke so a tripped condition cant be overridden by holding the arm down
- Manual weld check - provides a convenient test against welding of overload relay contacts
- Just depress the weld check operator to trip the relay, run a simple continuity test across the relay contacts, then depress the manual reset to return the starter to service
- Dual bimetals - anticipate overloads, responding to rising current and temperature with faster tripping on severe overloads for better motor protection
- Trip points are factory calibrated for accuracy
- +/-10% trip adjustment - by turning a dial in the overload relay face allows "tuning" the protection to the motor on the spot
