Order now the 194E-E16-1753-4G, a 16A IEC load switch designed for base or DIN rail mounting. This Allen-Bradley Bulletin 194E device provides a safe and efficient means of disconnecting electrical power from industrial machinery, featuring a localized handle for internal cabinet operation.
What Is the 194E-E16-1753-4G?
The 194E-E16-1753-4G is a 3-pole, 16 Ampere non-fused rotary disconnect switch. The «E» prefix denotes a base-mount configuration, often used inside control enclosures where the operator does not need to actuate the switch from the door, or where a shaft extension is used to reach a door-mounted handle. This specific model comes with a grey/black handle (1753-4G), making it suitable for standard operational switching rather than emergency stop functions. It is engineered for high durability, with mechanical life ratings exceeding 100,000 operations, ensuring longevity in high-cycle industrial applications.

Compatibility and Applications
The 194E-E16-1753-4G is highly compatible with the broader Rockwell Automation ecosystem. It is commonly used as a main disconnect for small control panels or as a local isolator for pumps and fans. Its compact frame size (36mm width) allows for high-density mounting on DIN rails. The switch architecture supports the addition of side-mounted auxiliary contacts (1 N.O. or 1 N.C.) for signaling the switch position back to a PLC or SCADA system.
Expert Tips
For applications where the switch is mounted deep in the cabinet, use the 194E-E16 in conjunction with a shaft extension and a NEMA 4X handle for external operation. This ensures that the cabinet door remains locked while power is on, complying with NFPA 79 requirements. If using this switch for motor isolation, always verify that the AC-23A rating matches your motor’s full-load current (FLC) and locked-rotor current (LRC) requirements.
Frequently Asked Questions
Q: Does this switch support padlocking?
A: The 1753-4G handle provided with this model is typically padlockable in the OFF position to meet safety standards for maintenance isolation.
Q: Can I use this switch for DC applications?
A: While primarily rated for AC, the 194E series has specific DC ratings for various voltages. However, you must consult the official Allen-Bradley technical data sheet for the derated DC current capacities before use.
