Product details

The 5SL3216-7MB: The C-curve trips at 5–10× rated current, so it handles moderate inrush from small motors, transformers, or lighting ballasts without nuisance trips — standard for general-purpose branch circuits in residential and light-commercial panels. The 4.5 kA interrupting rating at 400 V AC is the fault current it can safely clear; verify the available fault current at the installation point does not exceed that. The 2-pole construction switches both line conductors, suited for 230/400 V single-phase or two-phase loads where full isolation is needed.

Occupies 2 modular width units (36 mm) on standard 35 mm DIN rail. Depth 76 mm, height 90 mm, installation depth 70 mm. Mounting position any; sealable for tamper-proof applications. Halogen-free and silicon-free construction — suitable for environments with sensitive electronics or strict fire-load requirements.

Rated per EN 60898 for breaking capacity. Overvoltage category III, degree of pollution 2. Energy limitation class 3. Touch protection provided. Suitable for residential buildings and infrastructure installations per the manufacturer's designation.

Frequently asked questions

What is the breaking capacity of 5SL3216-7MB?

The 5SL3216-7MB has a 4.5 kA breaking capacity at 400 V AC per EN 60898.

How do I get pricing and availability for 5SL3216-7MB?

Submit an RFQ for the 5SL3216-7MB through the storefront; current pricing and availability are confirmed at quote time through independent distribution channels.

What is the difference between 5SL3216-7MB and 5SL6016-7KL?

The 5SL6016-7KL is a 1P+N (switched neutral) variant with a 6 kA breaking capacity at 230 V AC, versus the 5SL3216-7MB's 2-pole (both poles switched) 4.5 kA at 400 V AC. The 5SL6016-7KL occupies 1 MW unit (18 mm) versus the 5SL3216-7MB's 2 MW units (36 mm). Both are 16 A C-curve SENTRON breakers with the same 76 mm depth and 90 mm height.

Will 5SL3216-7MB drop into a panel specified for 5SL6016-7KL?

No — the 5SL3216-7MB is 36 mm wide (2 MW units) while the 5SL6016-7KL is 18 mm wide (1 MW unit). The panel would need the wider slot and both line conductors wired through the breaker.
