CITEL DS254E Series AC power Surge Protective Devices (SPD) are designed to meet all your surge protection needs for any low voltage installation. DS254E are to install parallel with with the low voltage supply line three phase lines 230/400Vac (3L/N).
- Type 1 + 2 unipolar surge protector
- Iimp total: 100 kA on 10/350µs impulse
- Imax : 140 kA on 8/20µs impulse
- Internal disconnections, status indicators
- Remote signaling
- IEC 61643-11, EN 61643-11 and UL1449 ed.4 compliance
