65	020	200
70	021	201
75	022	202
80	023	203
85	024	204
90	025	205
95	026	206
100	027	207
105	028	208
110	029	209
115	030	210
120	031	211
125	032	212
130	033	213
135	034	214
140	035	215
145	036	216
150	037	217
155	038	218
160	039	219
165	040	220
Nonstandard opening temperatures and bimetal resistances are available.

 

STEP 2:  Choose stat's terminal configuration Type A or B

STEP 3:  Choose Opening Temperature Tolerance

Plus or minus 5 degrees Celcius is standard

 

STEP 4: Determine Lead Configuration

Lead Wire Configurations
State-of-the-art automated lead processing can produce lead wires to meet customer application needs for overall length, terminated connectors and stripped length requirements! Please specify wire gauge, conductor type, insulation type, and strip length/termination type when ordering lead wire assemblies.

Lead Tolerances
Unless specified otherwise by the customer, the following tolerances apply to all assemblies.
Lead Lengths		Minimum Pull Tests
0" to 2"  2.1" to 6"  6.1" to 12"  12.1" to 36"  36.1" to 120"  Over 120"	+/-0.062" +/-0.125" +/-0.250" +/-0.500" +/-0.750" +/-1.000"	Wire ga.	Lead to Thermostats	Lead to AMP Terminal
		22-20 ga 18 ga. 16-14 ga	20 lbs 20 lbs 20 lbs	20 lbs 20 lbs 50 lbs

 

STEP 5:  Choose Insulating Sleeve

Sleeving
In order to achieve optimum heat transfer from the protected medium or ambient to the thermostat, the 7AM has been designed with the case connected to the bimetallic disc. However, this features also makes it necessary to electrically insulate the 7AM from the mounting surface.

Typically, this is accomplished with a Mylar sleeve available in 0.006-inch thickness, and marked with the part number. Custom markings and other sleeve materials can also be provided.

Contact Ratings
16VDC	20 ampres
115VAC	22 ampres
277VAC	8 ampres
600VAC	4 ampres
Ensure maximum contact needs, do not exceed these voltage/current combinations. These ratings are applicable for 10,000 cycles.
