E211X-16-20

What does this switch do?

This device is a modular ON/OFF control switch designed for installation in a distribution board. It is used for direct switching of electrical loads and includes a built-in visual indication feature, making it useful where clear local status indication is needed.

What is the contact configuration?

It is configured with 2 normally open contacts (2NO), with no normally closed contacts and no changeover contacts. This makes it suitable for straightforward ON/OFF switching duties.

Does it include a built-in indicator?

Yes. The switch includes 1 yellow LED indicator. On the ABB E211X-16-20, the indicator is designed for 115 to 250 V AC operation and helps provide quick visual recognition of the switch state.

What is the current rating?

The switch has a rated current of 16 A. It is intended for use in control and switching applications within its specified electrical ratings.

What voltage is it designed for?

It is rated according to EN for 250/400 V AC operation. The LED indicator version is intended for 115 to 250 V AC.

What types of loads can it switch?

This model is intended for switching mixed resistive and inductive loads, including moderate overloads, in frequent actuation duties. Its utilisation categories include AC-22A and DC-22A.

Can it be used with DC loads?

Yes, within its stated DC switching limits. The rated operational current is 16 A at 50 V DC and 1 A at 200 V DC, so the application should be checked carefully against the required DC load conditions.

How much space does it take in the panel?

The unit is 1 module wide, which corresponds to 18 mm. This makes it a compact choice for modular distribution boards where panel space is limited.

What conductor sizes can be connected?

The terminals are suitable for solid conductors from 1 to 6 mm², for two solid conductors up to 2 x 2.5 mm², and for flexible conductors from 0.75 to 2 x 2.5 mm², depending on the wiring arrangement.

What is the tightening torque for the terminals?

The recommended terminal tightening torque is 1.2 to 1.5 N·m. Correct tightening helps ensure a reliable electrical connection.

What is the protection rating?

The device has an IP20 degree of protection. This means it is intended for installation within an enclosure such as a distribution board rather than for exposed outdoor use.

What ambient temperatures is it designed for?

The operating ambient temperature range is -25 to +55 °C, and the storage temperature range is -40 to +70 °C.

Can the switch position be secured?

Yes. The switch is sealable in both the ON and OFF positions, which can be useful where controlled access to switching positions is required.

Which standards is it built to?

It is designed in line with several recognised standards, including EN 60669-1, EN 60669-2-4, IEC/EN 60947-3 and UL 508. This reflects its use as a modular low-voltage control switch for panel applications.

What applications is this type of switch commonly used for?

This style of modular switch is commonly used in distribution boards for controlling loads such as lighting, ventilation and air-conditioning circuits, especially where a compact footprint and visible indication are useful.
