What type of protection does this device provide?

It is a miniature circuit breaker (MCB) designed to protect electrical circuits against overloads (thermal trip) and short-circuits (magnetic trip).

How many poles does it have and what circuits is it suited for?

It is a 3-pole MCB, typically used for protecting three-phase circuits (for example three-phase feeders, distribution boards, and industrial loads).

What is the rated current?

The rated current is 80 A.

What does Curve C mean for tripping behaviour?

Curve C is intended for circuits with moderate inrush currents. The instantaneous (magnetic) trip range is typically 5 to 10 times the rated current; for an 80 A device that is approximately 400 A to 800 A for instantaneous operation.

What is the rated short-circuit breaking capacity?

The rated short-circuit capacity is 6 kA at 400 V AC (commonly stated as Icn, and also shown as Icu/Ics in the same 6 kA class depending on the standard applied).

What voltage is it intended to be used on?

It is intended for AC systems up to 400 V (for multi-pole applications). Maximum power-frequency recovery voltage is specified up to 440 V AC, and the minimum operating voltage is 12 V AC.

Which standards does it comply with?

It is designed to IEC/EN 60898-1 and IEC/EN 60947-2, supporting use in both building and industrial switchgear applications.

How is it mounted in a panel?

It mounts on a 35 mm DIN rail (EN 60715) using a fast clip mechanism. Mounting position can be any orientation, and supply can be connected from either direction.

What conductor sizes can be connected to the terminals?

The terminals accept large conductor cross-sections: up to 50 mm² for solid/stranded conductors, and up to 50 mm² for flexible conductors (product-dependent installation practices still apply). It also supports busbar connections up to 16 mm².

What tightening torque is recommended for the terminals?

The recommended terminal tightening torque is 3.0 N·m, using a No. 2 Pozidriv screwdriver.

What are the approximate dimensions and weight?

Typical dimensions are approximately 88.8 mm (height) × 69 mm (depth). As a 3-pole unit, overall width is about 52.5 mm (17.5 mm per pole). Net weight is approximately 0.42 kg.

What are the environmental operating limits?

Typical operating ambient temperature range is -25 °C to +55 °C, with storage down to -40 °C and up to +70 °C. As with most MCBs, current-carrying capability may require derating at higher ambient temperatures and when many devices are installed tightly side-by-side.

What is the degree of protection (IP rating)?

The device is IP20 as standard (finger-safe). When installed in an appropriate enclosure with a cover, it can achieve IP40 for the assembly.

Can it be combined with auxiliaries such as signalling or remote tripping?

Yes. The S200 range supports add-on accessories such as auxiliary contacts, signal/auxiliary contacts, shunt trips, undervoltage releases, and motor operating devices. This specific MCB (ABB order code 2CDS253001R0804) is compatible with those S200 accessory options.
