Citel DS134R-230/G SPD, type 1+2, AC, 3P+N, 20kA

Product Overview

The DS134R-230/G is an extreme-duty Type 1+2 surge protection device designed for electrical installation entrance protection in three-phase plus neutral networks. Featuring metal oxide varistor technology with pluggable modules, this four-pole unit delivers 12.5 kA impulse current per pole with 50 kA total capacity and 20 kA nominal discharge current for robust protection against direct lightning strikes. The DIN rail compatible design with optional remote signaling provides comprehensive common-mode protection for 230/400V TNS systems.

Key Features:

• Type 1+2 Combined Protection: Single device provides both Type 1 and Type 2 surge protection levels, eliminating need for separate coordinated stages while ensuring compliance with entrance panel requirements.
• High Impulse Capacity: 12.5 kA impulse current per pole (10/350 µs) with 50 kA total and 20 kA nominal discharge current for direct lightning strike defense.
• Pluggable Module Design: Individual replaceable protection modules per phase enable targeted maintenance and rapid field replacement without complete system disconnection.
• Enhanced TOV Withstand: Handles 335 VAC continuous and 440 VAC disconnection threshold with 20 kV lightning impulse withstand for reliable operation in high-stress environments.
• Individual Pole Indicators: Independent mechanical status indicator per pole provides immediate visual fault identification for efficient maintenance response.
• Common Mode Protection: L/N and N/PE protection paths with 1.3 kV and 1.5 kV protection levels ensure comprehensive system coverage.
• High Fault Current Rating: 25,000 A short-circuit withstand with internal thermal disconnection and Type S backup fuse coordination ensures safe operation.
• Optional Remote Signaling: Changeover contact available on DS134RS-230 variant enables integration with monitoring systems for centralized status tracking.
