DIN Rail Heavy Duty AC Surge Protective Device — Bulletin 4983-DH
Bulletin 4983-DH DIN Rail Heavy-Duty AC Surge Protective Devices
|
Features
- UL 1449
- Highest energy absorption capability of all Bulletin 4893 products
- Robust design avoids uneccessary replacement
- Visual fault indicator linked to internal thermal disconnect
- Automatic trigger for SPD replacement
- Safety remote signaling standard
Bulletin 4983-DH is a heavy-duty surge protector. This SPD combines a high-energy varistor (MOV) network with a gas discharge tube to increase performance in protection level, life duration, and suppression of leakage current. The Bulletin 4983-DH product is connected in parallel and can be located in the feeder circuit.
