Product Information
Full details
This Eaton Z-S Series bistable relay (MPN 265262) is designed for electricians and control system integrators needing reliable switching of consumers in momentum applications. Its key benefit is robust, rail-mounted operation with a 16A switching capacity at 250V AC. A potential caveat for some users is the 230V AC coil voltage, which requires a compatible power source.

FAQs
What is a bistable relay?
A bistable relay is a type of relay that remains in its last set position (either ON or OFF) even after the control power is removed. It requires a specific impulse or signal to change its state.
What does '1 NO contact' mean?
It means the relay has one contact that is 'Normally Open'. This contact is open (not conducting) when the relay coil is not energized and closes (conducts) when the coil is energized by a control signal.
Can I use this relay with a 12V DC control signal?
No, this relay has a 230V AC coil voltage and is designed to be operated by a 230V AC control signal. Using a different voltage or type (DC) will likely result in malfunction or damage.
What is the maximum load this relay can switch?
The relay has a maximum switching capacity of 16 Amps at 250 Volts AC.
How is this relay mounted?
It is designed for mounting on a standard 35mm DIN rail, which is common in electrical control panels.
What is the operating temperature range?
The relay can operate within a temperature range of -20°C to 45°C.
What does MPN 265262 refer to?
MPN stands for Manufacturer Part Number. 265262 is the specific identifier for this Eaton Z-S Series relay model.
Troubleshooting
Relay does not switch when coil is energized.
Verify the coil voltage is exactly 230V AC. Check that the control wiring to the coil (A1/A2) is correct and secure. Ensure the control signal is sufficient to energize the coil.
Contact is always closed or always open, regardless of coil signal.
The relay may be faulty. Check if the switching operation is mechanically obstructed. Ensure the load connected does not exceed the 16A rating, which could cause internal damage.
Relay switches intermittently or fails to hold state.
Check for unstable or fluctuating coil voltage. Ensure the control signal pulse duration meets the minimum requirement for switching. Inspect wiring for loose connections or intermittent faults.
Overheating of the relay.
Ensure the load current does not exceed the 16A rating. If the coil is continuously energized when it should not be, this can cause heat. Verify correct bistable operation wiring.
Pros and Cons
Pros
- Energy-efficient due to bistable operation.
- High switching capacity for its size.
- Standard DIN rail mounting simplifies installation.
- Reliable performance from a trusted brand (Eaton).
- Clear indication of contact status through its design.
Cons
- Requires a 230V AC supply for the coil, limiting compatibility with lower voltage control systems.
- Only provides one normally open (NO) contact, may require additional relays for more complex switching.
- Switching is not instantaneous; it requires a coil pulse to change state.
- Specific application suitability needs to be confirmed for 'momentum range' consumers.
Setup, Compatibility & Care
Setup:
- Mounting: Securely attach the relay to a standard 35mm DIN rail within your electrical enclosure.
- Wiring: Connect the control circuit to the coil terminals (typically marked A1/A2) using the specified 230V AC input. Ensure the power source matches the coil voltage precisely.
- Load Connection: Wire your consumer (load) to the normally open (NO) contact and the common terminal. The switching capacity must not exceed 16A at 250V AC.
Compatibility:
- Coil Voltage: Primarily compatible with 230V AC control circuits. It will not function correctly with other voltages.
- Input Frequency: Designed for a 50 Hz AC input frequency.
- Contact Rating: Suitable for loads within its 16A / 250V AC rating. Verify compatibility with inductive or capacitive loads, which may require specific considerations or external protection.
- Mounting Standard: Fits standard 35mm top-hat DIN rails.
Care:
- Environment: Operate within the specified temperature range of -20°C to 45°C.
- Cleaning: Keep the relay clean and free from dust and debris. Use a dry cloth for cleaning; avoid liquids or solvents. Ensure power is disconnected before any cleaning.
- Inspection: Periodically inspect wiring connections for tightness and signs of wear.
