NEMA coils are AC only. TeSys N comes with 120 VAC coils (24 VAC on Sizes 00–1). For a 24 VDC PLC output, use an interposing relay or the TeSys Deca Open Starter Selector. Type S adds Form S (separate control) automatically when the coil differs from the line.

Need it in an enclosure? Use the NEMA Enclosed Starter Selector.

Reference tables

Ratings by NEMA size Type S and TeSys N, Sizes 00–7

Digest 179 Tables 16.34, 16.80, 16.86 and 16.89. Size 1P is a Type S single-phase starter only. Size 7 is TeSys N only.

Open catalog numbers by size 8536, 8736, 8502, 8702, T36, T02

Type S: class + type + coil code + forms in alphanumerical order, for example 8536SCO3V02H30S (leave out H30 for melting alloy heaters). TeSys N: replace ●● with the coil code, G7 (120 VAC, Sizes 00–5), F7 (120 VAC, Sizes 6–7) or B7 (24 VAC, Sizes 00–1). "—" = not listed.

Overloads for TeSys N contactors LRD bimetal and LR9D electronic

Digest Tables 16.42 and 16.43. LRD = Class 10 with single-phase (phase-loss) sensitivity, LRD…L = Class 20. LR3D versions (without single-phase sensitivity) are for single-phase motors. LR9D: Class 5/10/20/30 selectable, Sizes 00–1.

Motor Logic dial ranges Type S forms and TeSys N T36

Digest Tables 16.315 and 16.40. A Size 1 T36 can be ordered with a smaller relay: add 0 (6–18 A), 9 (3–9 A) or 8 (1.5–4.5 A) before the coil code, for example T36CN130G7.

Class 2510 open manual starters Type F, Types M and T

Digest Tables 16.1, 16.3 and 16.16. Melting alloy heaters: Type F uses Heater Table 43 (one A-type heater, standard trip only); Types M and T use Table 1 (standard), Table 72 (quick) or SB slow-trip units, small-enclosure table (Table 2 / 73 for large enclosures). DC versions and Class 2511 reversing / 2512 two-speed starters: contact the A&C Team.

Coil voltage codes

All NEMA coils are AC. Type S: 24 VAC not on Sizes 4–6, and needs Form S on Sizes 00–3. TeSys N DC coils (BD) were discontinued; for a 24 VDC control signal, use an interposing relay or a TeSys Deca starter with a 24 VDC coil.

NEC motor full-load current Tables 430.248 & 430.250

Use the table current to size the starter and conductors (NEC 430.6(A)(1)). Set overloads from the motor nameplate FLA (NEC 430.6(A)(2)).
