BTA offers AC/DC switching applications

Aimed at OEMs, panel builders, CEMs, equipment manufacturers and the HandV industry, the BTA relays are available in two versions, the multi-pole BTA3, and the single-pole BTA5 version.

The BTA3 is available in two and three pole versions and both are available with changeover or N/O contacts.

The power relay has a 25A 300V AC contact rating in both the changeover and N/O versions.

The BTA5 is a single pole relay available as a one N/O + one N/C relay, or a N/O relay.

It is rated at 30A in both versions and has a high inrush current capability.

Both the BTA3 and the BTA5 have a 1HP motor rating and the N/O versions are supplied with a 3mm contact gap to EN60335-1.

The BTA3 is available either as a flange-mount version with 250 Faston (6.3 x 0.8mm) tabs; a plug-in version with 187 Faston (4.8 x 0.5mm) tabs using the DIN rail socket BTA3-113A-E; or as a PCB version supplied with PCB pins.

The BTA5 is available as a flange-mount relay with 250 Faston (6.3 x 0.8mm) tabs.

Both the BTA3 and the BTA5 have UL and CE approvals and are available in 6, 12, 24, 48, 110, 240V AC, and 6, 12, 24, 48, and 110V DC.

Operation times are AC 30m/s, and DC 20m/s, and electrical life is 100,000 operations for a power relay.

The relays are designed to operate in an ambient temperature of -30 to 50C.

Relays of a similar rating to the BTA series power relays are available but they are physically larger, or of a similar size but with a lower contact rating.

Switchtec holds the BTA power relays as a stock item and is able to provide full technical support via its field sales team throughout the UK.
