The DS201T series RCBO is a 1P+N in two-modules device for the protection of end user single-phase circuits against overload and short-circuit currents protection against the effects of sinusoidal alternating earth fault currents protection against indirect contacts and additional protection against direct contacts. DS201T meets the demand of a device suitable for installation in rolling stock equ

Ratings as published by ABB (abb.com product data, datasheet 9AKK107492A7772; shop.in.abb.com listing for 2CSR255188R1204, 14 Sep 2026). Verify critical parameters against the datasheet before specifying.
The letter after the sensitivity says which earth-fault currents the breaker can sense. Every type trips on a plain AC leak; the higher types also catch the leaks electronics produce. Same rating, different type, different price.
Type AC
Senses sinusoidal AC leakage only. Enough for lighting, geysers, heaters and plain socket circuits.
Type A
THIS UNIT
Senses AC and pulsating DC leakage, the kind inverter air conditioners, washing machines, UPS units, solar inverters and EV chargers produce. A Type AC unit can stay blind to those faults. Covers everything Type AC does. The safe default for a modern home.
Type A APR
Type A with high immunity to nuisance tripping: a short delay rides through lightning surges and switching transients. For circuits where a false trip costs more than the delay: servers, refrigeration, long cable runs.
Sensitivity is a separate choice: 30 mA protects people from shock; 100 mA and 300 mA units are for fire protection or as an upstream main. Type definitions per IEC/EN 61008 and 61009.
Read: Contactor Sizing for 400 V and 415 V Motors: kW to Amps, AC-3 Ratings and Overload Relays →
What size contactor do I need for a 7.5 kW motor?
A 7.5 kW three-phase motor at 400 V draws about 14.5 A, so a contactor rated at least 16 to 18 A at AC-3 is the usual choice, with an overload relay set to the nameplate current.
What is the difference between AC-1 and AC-3?
AC-1 is the rating for resistive loads such as heaters; AC-3 is the rating for switching squirrel-cage motors in normal duty. Motors are always sized on the AC-3 figure, which is lower.
How many amps per kW for a three-phase motor?
At 400 V, roughly 2 A per kW for small motors, falling towards about 1.8 A per kW above 30 kW, because larger motors run at a better power factor and efficiency. Use the nameplate for the exact figure.
Is ABB DS201T RCBO · 1P+N · 20 A · 30 mA · Type A · C curve · 6 kA · 2CSR255188R1204 genuine and warranty-backed?

Yes. Every ABB product on Elume is 100% genuine, sourced through authorised channels, and carries the manufacturer's standard warranty.

Do you deliver outside India?

Yes, to every country except Pakistan, North Korea, Iran, Syria, Cuba, Russia, Belarus and Afghanistan, and the Crimea, Sevastopol, Donetsk, Luhansk, Zaporizhzhia and Kherson regions. The delivery fee depends on weight and destination and is shown at checkout; international orders are paid by card in US dollars. The full rules are on our shipping page.

Is there a wholesale or bulk rate?

Yes. Orders of 15 or more pcs get a wholesale price below the listed Elume price, applied automatically and shown on every product page.
