Product Information
Full details
This ABB ON-OFF Switch Circuit Trip (model E211-16-10) is designed for distributors and electrical installations requiring reliable circuit control. Its key benefit is providing a single, robust ON-OFF switching function with a 16A rated current and 250V AC/DC voltage rating. A potential consideration is its single normally open (NO) contact, meaning it does not include any normally closed (NC) contacts for additional circuit configurations.

FAQs
What does '1 NO contact' mean?
It means the switch has one set of contacts that are normally open. When the switch is activated (turned ON), these contacts close, completing the circuit. When the switch is deactivated (turned OFF), these contacts open, breaking the circuit.
What is the difference between AC and DC voltage rating?
The 250V AC/DC rating means the switch is safe and effective for use in both alternating current (like household power) and direct current (like from batteries or specific power supplies) circuits, up to a maximum of 250 volts for either type.
Can this switch be used outdoors?
No, this switch has an IP20 rating, which means it is protected against solid objects larger than 12.5mm but offers no protection against water. It is designed for indoor, dry environments.
What is the 'switching capacity' of 3kA?
The 3kA (3 kiloamperes) switching capacity indicates the maximum short-circuit current the switch can safely interrupt without being damaged. This is a crucial safety rating for protecting the circuit and connected equipment during fault conditions.
How many modular spacings does this switch take up?
This switch has a width of 0.5 modular spacings, meaning it occupies half the space of a standard 1-module width device on a DIN rail.
What is the operating temperature range?
The switch can operate reliably in ambient temperatures ranging from -25 °C to 55 °C.
Troubleshooting
Switch does not operate (ON/OFF)
Verify that the circuit is powered and that the switch is correctly wired. Ensure the operating mechanism is not obstructed. Check for proper installation on the DIN rail.
Overheating during operation
Confirm that the circuit's current draw does not exceed the switch's 16A rating. Check terminal connections for tightness, as loose connections can cause resistance and heat. Ensure adequate ventilation around the switch.
Unit feels loose on DIN rail
Ensure the mounting clip at the bottom of the switch is properly engaged with the DIN rail. Check that the DIN rail itself is securely mounted.
Pros and Cons
Pros
- Reliable ON-OFF switching functionality.
- Suitable for a variety of AC and DC applications.
- Compact form factor for space-constrained installations.
- Designed with safety standards in mind (DIN VDE 0113).
- Robust construction for industrial use.
Cons
- Only one normally open (NO) contact, limiting complex circuit designs.
- No normally closed (NC) contacts available on this specific model.
- IP20 rating means it's not suitable for wet or dusty environments.
- Requires careful installation by qualified personnel.
Setup, Compatibility & Care
Setup:
This switch is designed for mounting on a standard DIN rail within an electrical enclosure. Ensure the power supply is completely disconnected before installation. Connect the circuit conductors to the appropriate terminals according to the wiring diagram and local electrical codes. It is recommended that installation be performed by a qualified electrician.
Compatibility:
- Voltage: Compatible with AC and DC circuits up to 250V.
- Current: Suitable for circuits with a rated current of 16A.
- Mounting: Designed for 35mm DIN rail mounting.
- Environment: Best suited for indoor, dry environments due to its IP20 rating.
Care:
- Regularly inspect the switch for any signs of damage or wear.
- Keep the surrounding area clean and free from dust and debris.
- Avoid exposing the switch to excessive moisture or extreme temperatures outside its operating range (-25 to 55 °C).
