Eaton 184762 - PKZM0-16 motor circuit breaker, 11-16 A, 3-pole
Eaton's PKZM0-16 motor circuit breaker (cat. no. 184762) is a compact device for reliable motor protection in the 11-16 A current range. It provides effective short-circuit and overload protection and the ability to manually switch the drive on and off.
- Current setting range of 11-16 A, suitable for typical three-phase motors.
- 3-pole design for three-phase grid applications.
- Short-circuit breaker with high breaking capacity for installation protection.
- Manual operation via a knob on the front of the apparatus.
- Compact housing suitable for DIN rail mounting.
- Compatible with Eaton PKZ/PKZM0 modular apparatus system.
Application and protective functions
The Eaton PKZM0-16 motor circuit breaker (184762) is designed for direct protection of three-phase motors against the effects of overloads, rotor blockage and short circuits. The thermomagnetic tripping characteristic allows the current range to be precisely matched to the motor power within 11-16 A, providing selective protection and reducing the disconnection time in the event of a short circuit. The device performs switching (manual switching on/off of the motor) and protection (overload and short-circuit) functions, which allows it to be used as a motor starter in simple apLictions of control. The apparatus can be used in drive systems of machines, fans, pumps, conveyors and other equipment operating in industry, construction and technical infrastructure.
Assembly, compatibility and extensions
The compact design of PKZM0-16 allows quick installation on a standard DIN rail in switchboards and control cabinets. The apparatus is compatible with a wide range of Eaton accessories, such as auxiliary contacts, undervoltage and surge triggers, surface-mount enclosures, and adapters for busbar systems. Thanks to the PKZM0 series' unified dimensional concept, it is possible to create extensive starting systems in combination with contactors and control elements, while maintaining mounting consistency and ease of retrofitting. Clear operating elements and status indicators on the front of the device facilitate expLoatation and diagnostics under industrial conditions.

FAQ (customer)
- Q: What motor power range can this PKZM0-16 be used for?
A: It is designed for motors whose rated current falls within 11–16 A; the exact kW value depends on the suppLy voltage and motor efficiency. - Q: Can I use this device as a simpLe ON/OFF switch for the motor?
A: Yes, it can be used for manual switching of the motor in addition to providing overload and short-circuit protection. - Q: Is it suitable for DIN-rail mounting in a standard distribution board?
A: Yes, the PKZM0-16 is designed for quick mounting on a standard DIN rail. - Q: Do I need additional fuses with this motor-protective circuit breaker?
A: In many appLications it can be used without separate fuses, but final coordination must follow local standards and system design requirements. - Q: Can it be combined with a contactor for remote control?
A: Yes, it can be combined with Eaton contactors to form motor starters with remote control capability. - Q: Is there an indication when the device trips due to a fault?
A: The front operator shows the tripped position, allowing quick identification of a fault condition.
FAQ (expert)
- Q: What is the tripping class of the thermal release for PKZM0-16?
A: The device uses a standard thermal characteristic suitable for general-purpose motor protection; consult the series documentation for detailed time-current curves. - Q: How should I coordinate this breaker with upstream protection devices?
A: Select upstream breakers or fuses according to the maximum prospective short-circuit current and use Eaton coordination tables to ensure selectivity and back-up protection. - Q: Can PKZM0-16 be used in combination with soft starters or frequency inverters?
A: It can be used for line protection, but motor protection may need to be provided by the drive; follow the drive manufacturer’s recommendations. - Q: Are auxiliary contacts for signaling trip and ON/OFF status available?
A: Yes, clip-on auxiliary contact modules are available for status and fault indication. - Q: How should the current setting be adjusted in relation to the motor namepLate?
A: Set the dial to the motor’s rated current from the namepLate within the 11–16 A range to ensure correct thermal protection. - Q: Is type-2 coordination achievable with standard Eaton contactors?
A: Yes, type-2 coordination is possible when following Eaton’s coordination tables for PKZM0 with the respective contactor types.
