[faq question=”What is the ABB A26-30-10 (200V 50Hz / 200–220V 60Hz) contactor used for?”]A26 contactors control 3-phase motors and general power circuits up to 690 V AC or 220 V DC. They are also suitable for isolation, capacitor switching, and lighting applications. This model is a block-type, 1-stack, 3-pole contactor with an AC coil.[/faq]

[faq question=”What does the designation A26-30-10 signify?”]“A26” is the series/frame. “-30” indicates 3 NO main poles (0 NC), and “-10” indicates 1 NO, 0 NC built-in auxiliary contact. The device has 3 main poles plus the single auxiliary as standard.[/faq]

[faq question=”What are the key current and voltage ratings?”]Rated operational voltage (main circuit) is up to 690 V AC. AC-3 Ie is 26 A at 220/230/240 V (55 °C); AC-1 Ie is 45 A at 690 V (40 °C). AC-15 Ie is 4 A at 220/240 V. Auxiliary circuit Ith is 16 A at 40 °C per IEC 60947-5-1. Rated insulation voltage Ui is 600 V (UL/CSA).[/faq]

[faq question=”What are the making/breaking capacities and switching speed?”]Per IEC 60947-4-1, AC-3 making capacity is 10 × Ie and breaking capacity is 8 × Ie. Per IEC 60947-5-1, AC-15 breaking capacity is 10 × Ie. The time from coil de-energization to NO contact opening is 4…11 ms. Maximum electrical switching frequency in AC-1 duty is 600 cycles/hour.[/faq]

[faq question=”What is the coil specification for this variant?”]This variant has an AC coil rated 200 V at 50 Hz and 200–220 V at 60 Hz with a laminated magnet circuit. Device frequency limits are 25…400 Hz; the supply coil itself is for 50/60 Hz. Coil consumption (average holding, 50 Hz): Refer datasheet / contact Shansen for confirmation.[/faq]

[faq question=”Is it suitable for capacitor switching (AC-6b)?”]Yes—AC-6b rated operational power (Pe) is 11.5 kvar at 230/240 V, 40 °C, 50/60 Hz. Verify kvar and inrush conditions for your bank design and protection scheme. For other voltages or ambient conditions, refer datasheet / contact Shansen.[/faq]

[faq question=”What auxiliary contacts and accessories are available?”]It includes 1 built-in auxiliary NO; additional auxiliary blocks can be front- or side-mounted. A wide range of accessories is supported (e.g., add-on auxiliaries, interlocks, etc.). Terminal type is screw—tighten to ABB-specified torque (refer datasheet).[/faq]

[faq question=”Which standards and compliance references apply?”]Ratings and test duties follow IEC 60947-4-1 (contactors) and IEC 60947-5-1 (control circuits). Rated insulation voltage Ui 600 V is noted per UL/CSA. For specific approvals/markings (UL listing, CE, RoHS), refer datasheet / contact Shansen for confirmation.[/faq]

[faq question=”What are the size/weight and environmental limits relevant to logistics?”]Package dimensions are approx. 115 × 101 × 61 mm with a gross weight of ~0.6 kg. Storage temperature is −60…+80 °C. For operating ambient limits, clearances, and mounting orientation, refer datasheet / contact Shansen.[/faq]
