The 6EP1961‑2BA11 is a 4‑channel electronic selectivity module for 24 V DC circuits up to 3 A per channel. If one branch overloads or shorts, only that channel trips — the other three continue supplying their loads without interruption. Each channel´s current threshold can be adjusted independently, and the electronic trip mechanism can be reset remotely or manually once the fault is cleared.

Selective Protection in a Compact Package

• 4 channels × 3 A: each channel monitors one 24 V branch circuit. The electronic trip characteristic is faster and more precise than a thermal‑magnetic breaker, reacting to both gradual overloads and dead shorts.
• No cross‑talk: channels are electrically independent downstream of the common supply. A fault on channel 2 does not pull down channel 1, 3 or 4.
