Product details

The Schneider Altistart 48 ATS48C32QS316 is a soft starter for asynchronous motors, rated 285 A at 230 to 415 V. It covers a wide motor power band — from 75 kW up to 250 kW — depending on whether you wire it in-line or in-delta, and whether the duty is standard or severe. The AC-53A utilization category tells you it's designed for frequent starts and stops typical of pumps and heavy industrial loads, not just occasional across-the-line starting.

Power Ratings & Connection Flexibility

The ATS48C32QS316 supports two wiring topologies: in the motor supply line (standard) or connected to the motor delta terminals. Each changes the effective power rating. For example, at 400 V in standard duty, it handles 160 kW in-line and 250 kW in-delta. At 230 V in severe duty, it's rated 75 kW in-line and 132 kW in-delta. This flexibility lets you match the soft starter to the motor's actual connection without oversizing.

Built-in Protections & Compliance

The unit includes phase-failure protection on the line side and thermal protection for both the motor and the starter itself — so it can serve as the motor overload device in many installations, eliminating a separate relay. It carries CE marking and is built to IEC 60947-4-2, the standard for AC semiconductor motor controllers and starters. That's the spec that governs coordination, short-circuit protection, and endurance for this class of device.

Frequently asked questions

What is the replacement for ATS48C32QS316?

The manufacturer has not published an official direct successor for this order code. For a current-production equivalent, you'll need to evaluate the Altistart 48 series replacement — typically the Altistart 22 or Altistart 01 families — based on your motor power and connection requirements. We can help cross-reference against an RFQ.

Where can I buy ATS48C32QS316?

This obsolete soft starter is not stocked on the shelf. We source it to order through independent distribution against an RFQ. Send us your request for a current price and availability quote.

What is the price of ATS48C32QS316?

Pricing varies with condition (new, new-in-box, used) and availability on the surplus market. We confirm the price at quote time against an RFQ — no published list price applies to obsolete stock.

Can ATS48C32QS316 be used for a 250 kW motor?

Yes, but only when connected to the motor delta terminals at 400 V in standard duty. At 230 V in-line, it is rated for 75 kW (severe) or 90 kW (standard). Verify your motor connection and duty class before specifying.

What standards does ATS48C32QS316 comply with?

It is CE marked and built to IEC 60947-4-2, the standard for AC semiconductor motor controllers and starters. That covers the coordination, short-circuit protection, and endurance requirements for soft starters in industrial environments.
