Draw-out circuit breaker with sentinel trip unit 66kA 800A 3P HW1E308DB

Universal protection for three-phase installations

This solution is dedicated to both professional installers and end-users, providing reliable protection against overloads and short circuits in networks with a voltage of 440‑690 V. Thanks to its withdrawable construction and the ability to connect conductors in a separate housing section, installation is quick and requires no specialized tools. A short-circuit capacity of 66 kA at 400 V/50 Hz ensures effective response even under the most demanding fault conditions.

Key benefits

• Rated current 800 A – enables protection of large industrial and commercial circuits without risk of circuit breaker overheating.
• Three poles (3P) – full protection of all phases simultaneously, eliminating the risk of single-phase tripping.
• Four changeover auxiliary contacts – allow connection of signaling or additional control elements without extra modules.
• Built-in trip indicator – provides immediate visual indication of the circuit breaker status, facilitating diagnostics and rapid service response.
• IP2X protection rating – protection against contact with live parts, meeting safety requirements for typical distribution boards.
• Optional motor operator – capability to be equipped with a motor drive for automatic opening/closing of the circuit when required.

Installation and compatibility

• Withdrawable construction allows easy adaptation to existing distribution boards and rapid field replacements.
• Main connections are made via a separate housing section, minimizing the risk of improper screw tightening and ensuring stable electrical contact.
• The product does not require mounting on a TH DIN rail and does not include a built-in motor operator – these functions can be added optionally, increasing flexibility in designing the protection system.
• Designed for TN‑S (sentinel) networks, complying with European standards for overcurrent protection and ensuring compatibility with other HAGER components.

Thanks to this well-engineered circuit breaker, installers gain ease of installation and technical certainty, while end-users benefit from stable and safe operation of the entire electrical installation.
