µ Overload Relay Code

Use to order solid-state overload relay. Do not use when ordering eutectic alloy overload relay. The cat. no. as listed is incomplete. Select an overload relay code from E1 Plus Solid-State Overload Relay
(Selectable Class 10, 20, or 30) (Automatic/Manual Reset) to complete the cat. no. Example: Cat. No. 505-AAD-µ becomes Cat. No. 505-AAD-A2D.

¬ Omission of Overload Relays — Bulletin 505 reversing starters are available without overload protection. Cat. nos. for all starters without overload protection will be the listed cat. no. with the No. 23 added. Example: Cat. No. 505-AOD-µ would be Cat. No. 505-AOD-23.
T Vertically Arranged — Full voltage reversing starters, sizes 0…5, open type without enclosure can be supplied in a vertically arranged construction. To order, change the bulletin number in the listed cat. no. from 505 to 505V. Example: Cat. No. 505V-AOD-A2D with solid-state overload relay and Cat. No. 505V-AOD with eutectic alloy overload relay.
‡ Fiberglass reinforced polyester hubs are included with each starter. Sizes 6…8 are painted enclosures.
§ Does not include line and load lugs. See Contactor Accessories for kits.
§ Price includes control circuit transformer. This applies to NEMA size 6 enclosed, only.
Ø Only available on sizes 00…5. When using 24V coils on size 4 or 5, an interposing relay may be required. See AC Coil Data values.
z When selecting a factory installed control circuit transformer (see Modifications for Non-Combination Devices), use the common control coil voltage code to denote the transformer primary voltage. The starter coil and transformer secondary voltage will both be 120V by default. Example: Cat. No. 505-BAB-6P will have a transformer with a 480V primary/120V secondary voltage and a 120V starter coil. If a starter coil voltage other than 120V is desired, a second coil voltage code must be added to denote the coil/transformer secondary voltage. Example: Cat. No. 505-BABJ-6P will have a transformer with a 480V primary/24V secondary and a 24V starter coil.
ª This coil is optimized for 110…115V, 50 Hz applications, but can be used at 120V, 60 Hz nominal.
v This coil is optimized for 115…120V, 60 Hz applications, but can be used at 110V, 50 Hz nominal.
ª This coil is optimized for 220…230V, 50 Hz applications, but can be used at 240V, 60 Hz nominal.
