Eaton 190021 - 1-pole surge arrester, type 3, 275 V AC
The Eaton 190021 surge arrester is a Type 3 1-pole surge protector designed to protect sensitive terminal equipment in 230/400 V AC low-voltage installations. It provides a high level of safety expLoatation due to its compact modular design and compliance with relevant IEC standards.
- Surge arrester class type 3 for protection of final consumer circuits.
- Rated voltage of 275 V AC suitable for 230/400 V networks.
- 1-pole design for protection of a single phase conductor.
- Modular design for DIN rail for easy installation in switchgear.
- Complies with the requirements of IEC/EN standard for type 3 SPD devices.
Surge arrester application and function
The Eaton 190021 surge arrester is designed to protect sensitive electrical equipment from switching and induced surges in low-voltage networks. It is used in final consumer circuits, such as circuits for plug sockets, lighting or power supply of electronic equipment, as a supplement to type 1 and 2 protection installed in the main switchgear. The apparatus reduces ampLituda surges to a level that is safe for the insulation and electronics of terminal equipment, which extends their life and reduces the risk of damage.
Design, installation and safety expLoatation
The device has a modular design suitable for mounting on a standard DIN rail in low-voltage switchgear. the 1-pole configuration allows flexible inclusion of the arrester in the phase path of the corresponding circuit, according to the installation design. The housing made of insulating material resistant to ciepLne and electrical stress ensures a high level of user safety and adequate mechanical-environmental durability. Connection terminals allow a secure and durable connection to the installation wires, reducing the risk of overheating and loosening of connections during expLoatation.

FAQ (customer)
- What is the purpose of the Eaton 190021 surge protective device? It is used to protect end-user equipment against transient overvoltages in low-voltage 230/400 V AC installations.
- Can I use this device in a typical home distribution board? Yes, it is designed for modular DIN-rail mounting and can be installed in standard residential distribution boards.
- Is the 190021 suitable as the only surge protection in the installation? No, it is a type 3 SPD and should be used as suppLementary protection to upstream type 1 and/or type 2 devices.
- How many conductors can I protect with this device? This specific model is 1-pole and is intended to protect a single phase conductor in an end circuit.
- Does the device require regular maintenance? Under normal conditions it is maintenance-free, but periodic inspection of connections and proper operation as part of routine installation checks is recommended.
- Can it be used for DC appLications? No, it is specified for AC systems with a nominal voltage of 275 V AC.
FAQ (expert)
- In which part of the protection concept should the Eaton 190021 be installed? It should be installed as a type 3 SPD in the final circuits, downstream of coordinated type 1 and type 2 SPDs located at service entry and sub-distribution levels.
- Is coordination with upstream SPDs required? Yes, proper energy and voltage coordination with upstream type 1/2 SPDs according to IEC/EN requirements is necessary to ensure reliable operation and device integrity.
- What nominal system voltage is the device optimised for? The nominal voltage of 275 V AC makes it suitable for 230/400 V TN and TT low-voltage systems.
- Can the device be used in multipole configurations? Yes, multipLe 1-pole units can be combined to protect several phases or phase and neutral, depending on the system design.
- What mounting environment is recommended? It should be installed in an enclosure or distribution board providing adequate IP protection, within its specified temperature and pollution degree range.
- How should conductor cross-sections be selected? Use conductor cross-sections and tightening torques in accordance with the SPD’s technical data and local wiring rules to ensure thermal stability of terminals.
