Surge protector Type 3 (D) MSB6-400 with audible signal. C561302

Surge protection for your installation

The MSB6-400 surge limiter is a device designed to protect electrical installations from the effects of surges that can damage connected devices. This is particularly important for sensitive electronic equipment such as audio-video systems, LED lighting or home automation. This model, from the MSB6 series, belongs to type 3 (D) limiter class, which means it provides additional protection after type 1 and 2 limiters have operated.

Characteristics and application

The MSB6-400 limiter is designed to operate in 230V AC networks. Its task is to discharge excess energy generated by surges to ground, thereby protecting connected devices. The use of a type 3 limiter is crucial where high protection accuracy and minimization of the risk of damage caused by even small surges are required. Thanks to its compact size and IP20 protection class housing, this limiter can be mounted indoors, e.g. in electrical distribution boards or next to protected devices.

Key features and benefits

• Protection for sensitive equipment: Protects electronic devices from damage caused by surges, which translates into savings and avoidance of downtime.
• Type 3 (D) – additional level of security: Acts as a complement to type 1 and 2 limiters, providing comprehensive protection for the installation.
• Suitable for 230V AC networks: Standard voltage in most home and commercial installations.
• High efficiency: Rated current In at 3kA and maximum impulse current Imax of 6kA guarantee effective protection against surges of varying intensity.
• Compact dimensions: Facilitate installation in limited space.
• Optical indication (/LD version): Some versions of the MSB6-400 model are equipped with an LED indicating the operating status of the limiter – informs about its correct operation or the need for replacement.
• Versatility: Suitable for both new installations and modernization of existing surge protection systems.

The MSB6-400 surge limiter is a reliable solution for anyone who cares about the safety of their electrical devices and wants to avoid costly repairs or replacement of equipment damaged by surges.
